How to Remove Query Strings From Static Resources

Anyone familiar with WordPress will probably not be new to the statement – “Remove query strings from static sources.” It mostly comes up as warnings in Pingdom and GTMetrix as well as other related tools used in checking our website’s loading time. You mostly find file versions on the end of the URLs of CSS and JavaScript codes, thus making it impossible for specific servers and proxy servers to cache query strings, despite the presence of a cache-control:public header.Thus, when you get rid of these cache query strings, you are improving your caching, and ultimately enhancing the loading speed of your website.Furthermore, you are also closer to fixing other problems that may be contributing to the speed of your site.

Although, the query strings are present in the system for a reason; to ensure that there is no problem with caching in events of updating style.css from one version to another.If the caching process is not managed correctly, and the cached version of the updated plugin is allowed to keep running, it may break the website until the cache is flushed entirely or the expiration of the cached resource.
